(Proverbs 2:2 KJV) So that thou incline thine ear unto wisdom, and apply thine heart to understanding;
We have the key vote in the election of our souls. We must “incline" (make attentive NASB) (7181) our ear. How do you do that? Have you ever noticed that when you get, for example, a new red car how suddenly you see red cars everywhere? You know what I mean. When something is on our mind we are more aware of it. So when we begin to deliberately focus on something we become more aware of it. Our expectations are key to what we get out of any encounter.
There is also a learning curve and a practice curve. Years ago when I was involved in a youth choir I had to learn parts. By practice I got better at reading music. I eventually was able to pick up a hymnal and come close to what it said to sing. There was a learning curve based on practice. For years now churches have been moving away from hymnals and going to big screens with only words supplied. I find it very hard to figure out anything but the melody now. I have stopped using the skill and it has faded.
If you have never spent much time reading the word, get started. Keep at it. Hearing what the Holy Spirit has to say gets better with practice and your hearing stays strong with practice.
